In this study, we designed and synthesized a number of novel pyrido[3,4-d]pyrimidine-thiazolidine-1,2,4-oxadiazole derivatives and investigated them in vitro for their inhibitory action toward epidermal growth factor receptor (EGFR) kinases and antiproliferative activity against two different cell lines, MCF-7 and A-549. When compared to the lead chemicals, 5-fluorouracil and erlotinib, some of the
在本研究中,我们设计并合成了许多新型吡啶并[3,4- d ]嘧啶-噻唑烷-1,2,4-恶二唑衍生物,并在体外研究了它们对表皮生长因子受体(EGFR)激酶的抑制作用以及针对两种不同细胞系 MCF-7 和 A-549 的抗增殖活性。与主要化学品 5-氟尿嘧啶和厄洛替尼相比,一些化合物表现出可接受的活性。其中,最有前途的化合物4d和4e对MCF-7和A-549细胞系均表现出有效的抗癌活性(剩余IC 50值分别为:1.97±0.28μM至8.14±0.52μM); 5-氟尿嘧啶和厄洛替尼在这些细胞系中的比较 IC 50值分别为 5.56 ± 0.34 μM、12.66 ± 0.76 μM 和 3.64 ± 0.49 μM、9.54 ± 0.75 μM;以及优异的激酶抑制活性(EGFR:IC 50 = 0.34 ± 0.07 μM 和 0.42 ± 0.06 μM),比传统药物厄洛替尼(IC 50 =
